VALVE AND CATCH POCKET.

Application filed June 6,

To all whom it may concern:

Be it known that I, GUY C. Camus, a citizen of the United States,residing at Waycross, in the county of Ware and State of Georgia, haveinvented certain new and useful In'iprovements in 21 Valve and CatchPocket, of which the following is a specification.

This invention relates to a valve and catch pocket structure and itconsists in the novel features hereinafter described and claimed.

An object of the invention is to provide a structure oi the characterstated adapted to be used for feeding exhaust oil and water from thesteam end of an air pump to the air end thereof by suction created atthe air end of the pump.

In the accompanying drawing 1-- Figure 1 is a side view of a pump withthe valve and pocket connected thereto. Figure 2 is a transversesectional the pocket.

Figure 3 is a horizontal sectional the pocket.

Figure 4 is a vertical sectional view of the valve.

Figure 5 is a transverse sectional view of the valve.

As illustrated in the accompanying drawing, the pump comprises a steamcylinder 1 and an air cylinder 2, the steam pipe 3 connects with one endof the cylinder 1 and an exhaust pipe l also connects with saidoyliudor 1. A pocket 5 is connected in the pipe 4 and a pipe 6 connectsthe pocket 5 with the cylinder 2. The pocket 5 is provided with alongitudinally disposed partition wall 7 located in the lower portionthereof and which divides the lower portion of the pocket into chambers8. A boss 9 is located at one side of the partition 7 and connects withthe pipe 6 as shown in Figure 1. A plurality of bosses 10 is located atthe opposite side of the partition 7 and a plurality of pipes may beconnected with the bosses 10 when it is desired to connect the pocketwith a compound pump or a series of pumps. A valve structure 11 isconnected in the pipe 6 and said structure includes acasing 12 having apartition 13 located therein, the said partition being provided view ofview of 1924. Serial No. 718,358.

with a central opening lt. A nipple 15 is screwed in the lower end ofthe casing 12 and a ball 16 is housed within the casing 12 and restsupon the upper end of the nipple 15 and normally closes the mainpassageway through the nipple. Ducts 17 lead in from the upper end ofthe nipple 15 and communicate at their lower ends with the passageway 18through the nipple 15 at points below the ball 16.

During the operation of the pump the water and oil which is exhaustedfrom the cylinder 1 is connected in the pocket 5 and passes down throughthe pipe 6 and enters the cylinder 2 when suction is created therein.The oil and water passes through the opening 14 in the partition 13 ofthe easing 12 and flows down over the ball 16 and passes through theducts 17 into the passageway 18 in the nipple 15. lVhen back pressure iscreated in the pipe 6, the ball 16 is lifted by said pressure and closesthe opening 14 in the partition 13 thereby interrupting the flow of oiland water through the casing 12.

Thus it will be seen that simple and efficient means are provided forpassing the exhaust water and oil from a steam cylinder to an aircylinder for the purpose of lubrieating the operating parts in the aircylinder.

Having thus described the invention, what I claim is 1. In combinationwith a pair of cylinders, an exhaust pipe connected with one of thecylinders, a pocket connected in the exhaust pipe, a pipe connecting thepocket with the other cylinderya check valve connected in the lastmentioned pipe, the said check valve having by-pass ducts communicatingwith the passageway therethrough.

2. A. valve comprising a casing having a partition provided with acentral openin a nipple screwed in the casing and provided with apassageway, a ball housed in the CQS', ing below the partition andnormally closing the passageway through the nipple, the nipple beingprovided at its inner end with by-pass ducts which communicate with the,passageway at points below the ball.

In testimony whereof I aflix my signature.

GUY C. VALLIS.
